To all whom it may concern Be it known that 1, FRED s'. time, a

citizen of the United States, residing at'the city and county of San Francisco and State of California, have invented new and useful Improvements in Carburetors, of which. the

following is a specification. g

This invention relates tocarbureters of the type used for converting the ordinary grades of gasolene into a combustible mixture suitable for cooking, heating, lighting and other purposes. The object is to simplify and improve the construction and operation of the carbureting apparatusl' some is exemplified in the following de-- scription and illustrated in theaccompany- 'primary gasometer A and a secondary gas-.

ometer B, placed side by side, and each made up of a double walled lower stationary tank 12 and a double walled upper movable bell section 13, the latter-havlng its outer wall telescopically received in a water seal l4between the double walls of the stationary tank a and its inner wall (spaced inwardly from the inner wall of the stationary tank and carrying at, its lowerend a cloth or screlpn hood 15 secured to the bottom of the tan y A and B are cylinders 16 and 16 respectively, open at theirupper ends, and having communications at their lower ends with I Specification of Letters JPaterit.

One form which my invention may as-',

Surrounding the upper end of the cylin der is a perforated dish 21 forming a charged from the cylinder.

inder and spaced therefrom, with a packing 23 ofloof or other suitable spongy material into which the fuel from the dish falls. The

object is to saturate the packing with gasolene and then by passing airtherethrough to atomize the liquid. 1 The air supply for the carbureter is introduced through a pipe 24 at the inner end ofwhich is an upwardly opening check-valve 25.

In the case of the first gasometer, .a vaporizer or auxiliary carbureter 26 is added to pick upthe gasolene collected at the hot tomof the main carburetor from the drip- I v pings of the packing 23. .This vaporizer is bestshown in Fig. 2 and'comprises an air inlet pipe 27 with a check valve 28 and a cup 29 encircling the cylinder 16 and ar-:

ranged beneath'ia conical deflector 30., which latter directs the'gasolene' from the packing into the cup. This plate is frusto-conical and is secured by its enlarged lower-edge to t-hewall ofthe casing. Theupper opened end of the partitionsurroundst e cylinder 16 and is spaced therefrom to form an annular passageway. The-plate thus arranged.

provides a V-shaped groove into which the surplus liquid fuel will fall and from which I it may be drained by the tube 30 which com- 4 municates with the cup therebeneath. Within the-cup is a series of vertically arranged plate 32, this plate forming afalse bottom for, the cup,

said nozzles having communication with a space below the false bottom. A series of curved nozzles 33for the fuel are carried by the plate with their lower. ends spaced above ;the same and their upper ends passing into close proximity. with the air nozzles, whereby theair in passing throught the nozzles 31 under the suction creatediby the rising nozzles 33 and atomizes the same. The gaseous mixture drawn through the a packing 23 enters the bell of the gasometer top thereof, and, in the ease of the first gasofthebell draws the fuel up through the ometer, the supply pipe 24 for the second. gasometer is connected therewith, while in *thecase of the second gasometer, suitable small level of liquid fuel precipitated in the connections "35 are lowermost posit1on.- ,The screen this be? comes saturated and as the'i'vaponfr m' h .the second gasometer.

bell'passes therethrou-gh it will be enriched and a considerable. portion of the precipitated fuel will thus be taken up; When the level of the liquid in the bottom of thetank A -becomestoo high, it is. drawn 011' by; an overflow pipe .36;

liquid is collected to a predetermined level and allowed to fiow into the supply tank 18' through a'pipe39. Avalved discharge pipe 40 communicates with the bottom of" the trap and is'fcontrolled-by a gravity apparatus-41,- which, when' the liquid in the trap becomes. too heavy for further use opens to allow the same ed to me November 23rd,'1915, and need not be further described herein.

The overflow the other leading to the supply tank beneath A. valve 44-is placed in the connectlons .to control the passage of I fuel through these branches to retard the .flow'of liquid to the'pipe 43 and cause it to overflow through the pipe 42. Thus the pre cipitated 'gasolene of the second gason'ieter will be returned to the supply tanks for further and later carburization', while the pre 'cipitation of the first gasometer will be returned for reuse sufficiently volatile for carburiz'ation and the residue which isfree ln'so far only as: it remains of all particles that could beatomized will be discharged into l cylinder 16 with the drain .pipef40. It is desirable,

0nd carbureter, and

therefore I provide the tlonywith which communicates atube145 Thus tion is bro en and the charge of gasolene drawn-in thereby .Irestricte It now remains' t'o' describe the automatic bells whereby the gasolene is pumped in and carbureted and trans- Y nected by second gasomethe first ga'someter is cona rod 46 to a piston 47 workin In a cylinder 48 which is fitted at its lower ter. The bell of provided to draw ofl the contents, either for immediate consumption bell'; is in its This fpipe in the case of v:When thebells are'nearing the firsttank A runs-to a trap 38-where the to be drawn ofl. Thisgravj i'ty valve is shown and described-in United 7 States Letters Patent, No..1,161,243, grantpipe of the. second tank B and 43, one leading to the from the bell ofthe first however, to limit the quantity, of gasolene introduced into the seea port near its. middle p'oriston "reaches the' port the sucnate'ly establishes communication between the pipe-49 and supply pipe and discharge conduit. The handle of the valve is connected to a lever 53 actuated by a cable 54, the latter running over sheaves 55 and connect- ,ed to-the piston 47. The bell of the second gasometer has connected to it a cable 56 running to a lever 57' which actuates a valve 58 located in the discharge pipe 51 behind the two-way valve 52. The connections between the cables 54 and 56 and their respec- :t1ve levers are such as to secure an actuation of the levers in both directions and at times movements.- his is accomplished by allow thelevers and providing spaced blocks 60 and weights 61, to limit the relative-movement between cables and le-' vers.-

' The bells of the gasometers are both in their lowermost positions when starting, at which time the valves will be open to admit water to the lower portion of the cylinder 48. The piston is thus raised, lifting the bell of the firstgasomete'r and the weight 61 on the end of the cable draws the latter down vjuntil the block thereon strikes the lever 53 and. depresses the latter, thus causing the valve "52 to be turned to position where the supply is cut 011' and the discharge opened. This permits the Water to escape cylinder, and the piston is-gradually lowered by the weight of the bell. The gasometer is weighted to prestransferred from the first gasometer to the second will be sufiicient to raise the bell of the second gasometerf The latter, when in raised position, will, through its connections, close the valve 58 against the escape of 'water from the cylinder 48. Until the gas is drawn off from the second -gasometer to permit the bellthereof to set position unless the second bell has settled sufliciently to open the discharge valve 58. The gasolene, which has trickled through the packing 23 of the first carbureter without becoming vaporized, will naturally be of a heavier grade and by introducing fresh air thereto through the auxiliary carbureter 26,. in the manner shown, many ofxthe heavier hydrocarbons will be atomized.

The water-seal of the gasometers, in addi ,tion to preventing leakage of gas, will abso'rb heat from the surrounding atmosphere, g and from repeated agitation due to ing and falling of the bells will transmit the ends of theirthe ris this heat to the inner walls of the tanks which tend to become quite cold due to evaporation of the gasolene.

Various changes in the construction and arrangement of the several parts herein shown and. described may be employed without departing from the spirit of my invention as disclosed-in the appended claims.
